When trying to change my Exchange 2010 receive connector to match my Reverse DNS PTR record I get an error message
:If the authmechanism attribute on a receive connector contains the value ExchangeServer, you must set the FQDN parameter on the Receive connector to one of the following values; ~.local or NETBIOS.
I am trying to match the Reverse DNS PTR because we get a #554 5.7.1 Message refused by ForgedIP check NDR from one particular server.
We have a valid PTR record that matches the outgoing FQDN. How can I make the Receive connector use my internet domain FQDN?
